I have all three in my roster, and I think it's not good to have so many players from the same team in the same roster.
I don't want to trade Foye because I like him, but I think Miller can be a good player (in fantasy terms).
Should I try to move Gomes? What could I ask for him?

you are right that miller is (in fantasy terms a good player) and also very right that this is not the time to move foye. This is because is you check his season splits he came back from his injury and by april was almost living up to being traded for roy (foye got 18 pts 5ast 3reb and 1 stl) he could very well come back next year and average over 20 pts

Well, I'm thinking in throwing Gomes to waivers so I will have another seat for a rookie.
I'm 4th to choose in my league's draft, so I suppose I will take Mayo or Eric Gordon. I would prefer mayo.
Would you choose another one in the fourth place, knowing that the first and the second will be rose and beasley?
